The Outsiders

The DCEU’s Batman took a break for a while, most likely after Robin’s death. When he returned, he refused to work with others. So it wouldn’t make sense to have the Outsiders appear yet, especially since the Dark Knight formed the team.

It all depends on when The Batman is released, as well as what happens in the DCEU until that time. We know that the Caped Crusader will work alongside other heroes in this year’s Justice League, so, depending how the movie ends, Bruce Wayne might go on to form his own team.

As a part of such a team, Serkis could play Metamorpho, who can transform his body into any elemental compound. So this would be another motion-capture role for the actor.
